    Default Winterizing and gasoline question

    Unfortunately, I didn't got as much we would have liked the last month and half. Which means I have half tank of fuel in the tank. I add startron fuel stabilizer each I time added fuel. Saddest time year, will I have any issues with the fuel next year. The shop told me they wil stabill to the fuel when they winterize it next week. Anyone see problems with this? Thank you

    No, but I would ask them if what they add also addresses Ethanol.

    I have always filled the tank (as well as adding stabilizer) at winterization time and never had any problems before. Most of the "experts" suggest filling the tank so I have always done that as a rule.

    I always fill the tank. Since you add stabilizer every time you gas up you do not need to run the engine after you add stabilizer then top off the tank. If you are putting in gas that has ethanol you need to make sure you top off your tank since ethanol absorbs water from the air. The more room left in the tank means the more water that can be absorbed into the tank causing issues the next year.

    Its actually the other way around with Ethanol blended fuel. A gallon of ethanol blended fuel can absorb X amount moisture. The more gallons in the tank, the more water that can be absorbed. The old ways of thinking have changed with the increased distribution of ethanol blended fuels.

    I like to run mind down as far as I can. Then I siphon gas out all off season for the dirtbikes. Fill with fresh in Feb when we start up again. Works great.

    I've been boating for almost 40 years now.I used to put my boats away with a full tank.About 5 years ago I switched plans.Now I siphon as much gas out as I can get when I put them away.In the spring I fill with fresh gas.No issues yet.

    Can't remember if it was a separate article or a post on this forum, but years ago there was well qualified information suggesting it's the interaction with air that causes fuel to become unstable. Therefore I fill the tank right to the top of the filler neck each fall and it's ready to go in the spring. Stabilizer is added during winterization process by the dealer, but that article indicated that in the absence of air space, stabilizer has no benefit so is not even required.
    If so, stabilizer producers are giggling all the way to the bank.
